code review 7213044: exp/locale/collate: moved low-level collation functionality

exp/locale/collate: moved low-level collation functionality
into separate package.  This allows this code to be shared
with the search package without the need for these two to use
the same tables.
Adjusted various files accordingly.

I glazed over after the first few files. Assuming it's mainly the move.
